According to an exemplary embodiment, the display device 110 may divide a basic advertisement display and a personalized advertisement display and may provide advertising content. The basic advertisement display provides a common advertisement that does not target a user, and the personalized advertisement display unit provides an advertisement that targets a user.

According to an exemplary embodiment, when a plurality of the terminals 120 are located in the vicinity of the display device 110, the display device 110 may divide a display screen into parts and may provide advertising content that is to be provided to users of the plurality of terminals 120 through the parts of the display screen.

A display apparatus and method of providing advertising content will now be explained in detail.

FIG. 2 is a block diagram illustrating a configuration of the display device 110 for providing advertising content, according to an exemplary embodiment.

According to an exemplary embodiment, the display device 110 may include a communication unit 210 (e.g., communication interface), an advertisement obtaining unit 220 (e.g., advertisement obtainer), a control unit 230 (e.g., controller), and a display unit 240 (e.g., display). However, all of the elements illustrated in FIG. 2 are not essential elements. According to one or more exemplary embodiments, the display device 110 may include more or less elements. The illustrated elements will be described below.

According to an exemplary embodiment, the communication unit 210 may communicate with a plurality of terminals that are located in the vicinity of the display device 110. The communication unit 210 may allow a pairing to be formed between the display device 110 and each of the plurality of terminals.

The communication unit 210 may allow a first pairing to be formed between a first terminal among the plurality of terminals and the display device 110.

According to an exemplary embodiment, the communication unit 210 may periodically broadcast an advertising message including an ID. A terminal that is located in the vicinity of the display device 110 may receive the advertising message and may recognize the ID in the advertising message. The terminal that is located in the vicinity of the display device 110 may form a pairing with the display device 110 by transmitting an ID and information of the terminal to the communication unit 210. The communication unit 210 may transmit advertising content to the terminal that is located in the vicinity of the display device 110.

According to an exemplary embodiment, once the first pairing is formed between the display device 110 and the first terminal, the communication unit 210 may transmit an ID of the first terminal to the advertising server 130. The advertising server 130 may receive the ID of the first terminal, and may detect first shopping propensity information (e.g., shopping habits) corresponding to the ID of the first terminal. The first shopping propensity information may be information that is previously registered by a user of the first terminal or data that is accumulated as the user of the first terminal shops.

According to an exemplary embodiment, the display device 110 may form pairing with each of a plurality of terminals. The communication unit 210 may periodically broadcast an advertising message including an ID of the display device 110. The plurality of terminals may receive the advertising message, and may recognize the ID of the display device 110 in the advertising message. The communication unit 210 may receive IDs of the plurality of terminals from the plurality of terminals. The communication unit 210 may transmit the received IDs of the plurality of terminals to the advertising server 130. The advertising server 130 may receive the IDs of the plurality of terminals, and may detect shopping propensity information of a plurality of users corresponding to the IDs of the plurality of terminals. The advertising server 130 may classify the plurality of users based on the detected shopping propensity information into groups in each of which users having the same shopping propensity are grouped together.

According to an exemplary embodiment, the advertising server 130 may be provided in the display device 110 or may be provided as an external apparatus that is physically separate from the display device 110.

According to an exemplary embodiment, the advertisement obtaining unit 220 may obtain first advertising content that is searched for from the advertising server 130 based on the first shopping propensity information of the user of the first terminal. The first shopping propensity information may include at least one of a purchased product, a store, a time of purchase, a payment method for the purchased product, and interests of the user of the first terminal.

According to an exemplary embodiment, the advertisement obtaining unit 220 may obtain advertising content that is searched for each group from the advertising server 130 based on the groups using the shopping propensity information of the plurality of users corresponding to the plurality of terminals.

According to an exemplary embodiment, the control unit 230 may allocate the first advertising content to a first region among a plurality of regions of the display unit 240 based on a first distance and the first pairing time. The first distance is a distance between the first terminal and the display device 110. The plurality of regions are regions that are obtained by dividing a display screen of the display device 110.

According to an exemplary embodiment, at least one of area of the plurality of regions and a number of the plurality of regions may be adjusted based on a distance between the display device 110 and a terminal that forms a pairing with the display device 110 and a duration for which the pairing is maintained.

For example, the number of the plurality of regions may be determined according to a number of terminals that are located in the vicinity of the display device 110. A terminal that is located in the vicinity (e.g., within a predetermined distance) of the display device 110 may be determined in consideration of a “distance between the display device 110 and the terminal” and a “duration for which a pairing formed between the display device 110 and the terminal is maintained”. When the terminal is located in the vicinity of the display device 110 for a period of time that is less than the period of time for which advertising content is to be provided, a user of the terminal may not observe an advertisement provided by the display device 110 until the preview of the advertisement is completed. Accordingly, the display device 110 may provide advertising content in consideration of a pairing time between the display device 110 and the terminal.

According to an exemplary embodiment, while an advertisement is displayed on the display device 110, the areas of the plurality of regions may be adjusted based on a distance between the display device 110 and a terminal. For example, a distance between the display device 110 and the first terminal may be referred to as the first distance and a distance between the display device 110 and a second terminal may be referred to as a second distance. A region that targets the user of the first terminal may be referred to as the first region and a region that targets a user of the second terminal may be referred to as a second region.

The display device 110 may determine the areas of the plurality of regions so that the areas of the plurality of regions are inversely proportional to a distance between the display device and a terminal. When the first distance is less than the second distance, an area of the first region may be adjusted to be greater than an area of the second region. Advertising content may be more efficiently provided to a user of a terminal that is close to the display device 110.

Conversely, the display device 110 may determine the areas of the plurality of regions so that the areas of the plurality of regions are proportional to a distance between the display device 110 and a terminal. When the first distance is greater than the second distance, the area of the first region may be adjusted to be greater than the area of the second region. Therefore, advertising content may be efficiently provided even to a user of a terminal that is far from the display device 110, because it is harder to see the display from farther away.

Before the display device 110 starts advertising, the areas of the plurality of regions may be adjusted based on a distance between the display device 110 and each terminal. Because an area of a portion of the display device 110 on which an advertisement is delivered is limited, the display device 110 may determine a number and areas of regions where advertisements are to be provided based on a distance. The display device 110 may consider a pairing time between the display device 110 and each terminal. The display device 110 may exclude terminals whose pairing times are equal to or less than a predetermined period of time, and may determine a number and areas of a plurality of regions by targeting only terminals whose pairing times are greater than the predetermined period of time.

According to an exemplary embodiment, the control unit 230 may allocate a plurality of pieces of advertising content, which are to be respectively provided to the plurality of terminals, to the plurality of regions. The control unit 230 may allocate advertising content for each group to one of the plurality of regions based on a “distance between a representative terminal for each group and the display device 110” and a “duration for which a pairing that is formed between the representative terminal and the display device 110 is maintained.”

According to an exemplary embodiment, the display unit 240 may display the first advertising content on the first region.

According to an exemplary embodiment, the display unit 240 may display the plurality of pieces of advertising content, which are to be respectively provided to the plurality of terminals, on the allocated regions.

According to an exemplary embodiment, the display device 110 may further include an input interface. A user of a terminal may input the user's command to the display device 110 through the input interface. For example, the first advertising content for the user of the first terminal may be displayed on the first region of the display device 110. When the first advertising content is about a “camera of a brand A”, the user of the first terminal may input a “model of the camera of the brand A” on the first region of the display screen through the input interface.

When an item needs to be selected by the user of the first terminal who observes the first advertising content, the user of the first terminal may select the item through the input interface.

According to an exemplary embodiment, the display unit 240 may display content corresponding to the input of the user of the first terminal on the first region.

According to an exemplary embodiment, the display device 110 may transmit at least one of the first advertising content and an electronic voucher that is related to the first advertising content to the first terminal. For example, “advertising content related to a camera” may be provided on the display screen of the display device 110. The display device 110 may transmit an “electronic voucher related to the camera” to the first terminal. Examples of the “electronic voucher related to the camera” may include a discount electronic stamp and an electronic coupon related to the camera.

According to an exemplary embodiment, the display device 110 may transmit the electronic voucher that is related to the first advertising content to the first terminal based on a “distance between the display device 110 and the first terminal” and a “duration for which the first pairing that is formed between the display device 110 and the first terminal is maintained”.

According to an exemplary embodiment, the display device 110 may control operations of the communication unit 210, the advertisement obtaining unit 220, the control unit 230, and the display unit 240 by using a central arithmetic processor. The central arithmetic processor may be an array of logic gates, or may be a combination of a general-purpose microprocessor and a memory in which a program that may be executed in the microprocessor is stored. Also, it will be understood by one of ordinary skill in the art that the central arithmetic processor may be any of other types of hardware.

Various operations or applications of the display device 110 will be explained below. It will be understood by one of ordinary skill in the art that if any of the communication unit 210, the advertisement obtaining unit 220, the control unit 230, and the display unit 240 is not specified, each operation or application that may be clearly understood or expected by one of ordinary skill in the art is within the scope of the present disclosure, which is not limited by names or physical/logical structures of specific elements.

FIG. 3 is a view illustrating advertising content that is displayed on a display screen of the display device 110 according to an exemplary embodiment.

According to an exemplary embodiment, the display device 110 may divide the display screen into a plurality of parts, and may display advertising content on the divided parts.

As shown in FIG. 3, the display screen of the display device 110 may be divided into regions having various areas.

According to an exemplary embodiment, a common advertisement may be displayed on a region 310 that is the largest among the regions of the display screen of the display device 110. The common advertisement may be an advertisement displayed on all terminals, rather than a specific terminal. Personalized advertisements considering terminals may be displayed on other regions 320, 330, and 340. Exemplary embodiments are not limited to this arrangement.

According to another exemplary embodiment, an advertisement that targets a terminal whose distance to the display device 110 is the smallest or whose pairing time is the longest may be displayed on the region 310 that is the largest among the regions of the display screen of the display device 110.

According to an exemplary embodiment, the display screen of the display device 110 may be divided into regions before advertising is started. A number of advertisements that are to be provided may be determined by detecting terminals that are located in the vicinity of the display device 110. The display device 110 may divide the display screen in consideration of the determined number of the advertisements. The display screen may be divided into a plurality of regions having the same area or different areas.

The display device 110 may divide the display screen in consideration of a distance between the display device 1410 and each of the detected terminals that are located in the vicinity of the display device 110. The distance is a distance between each detected terminal and the display device 110. For example, the display device 110 may display advertising content, which is to be provided to a user of a terminal at a shortest distance, on a largest region and may display advertising content, which is to be provided to a user of a terminal at a farthest distance, on a smallest region.

According to another exemplary embodiment, an area of a portion of the display screen of the display device 110 where advertising is performed may be resized while an advertisement is provided. That is, the area of the portion where advertising is performed may be adjusted in consideration of a state between a terminal and the display device 110.

For example, a distance between the first terminal and the display device 110 may be referred to as the first distance, a distance between the second terminal and the display device 110 may be referred to as the second distance, and a distance between a third terminal and the display device 110 may be referred to as a third distance. When advertising is started, if distances are short and increasing in an order of the first distance, the second distance, and the third distance, the display device 110 may display first advertising content, which is to be provided to the first terminal, on the region 320, second advertising content, which is to be provided to the second terminal, on the region 330, and third advertising content, which is to be provided to the third terminal, on the region 340.

While an advertisement is provided, each distance may be changed. When the first terminal is moved away from the display device 110 and thus the first distance is changed to the shortest, the display device 110 may increase an area of the region 330 and reduce an area of the region 320. As the areas of the region 320 and the region 330 are respectively reduced and increased, the display device 110 may move the region 340 to a portion that is left after the area of the region 320 is reduced.

According to another exemplary embodiment, the display device 110 may receive an input of a user through the input interface. For example, the user may select a desired advertisement through the input interface. Also, if a user wants to select an item in the advertisement, the display device 110 may receive an input of the user through the input interface. In this case, the input interface may be an input interface that may be touched on the display screen of the display device 110. The input interface may be a terminal that is used by the user. The user may directly input information to his/her terminal and may transmit the information to the display device 110.

For example, as shown in FIG. 3, an advertisement about a mobile phone is provided on the region 320. A user who observes the advertisement about the mobile phone may touch the region 320 to obtain detailed information and may obtain the detailed information about the mobile phone. The display device 110 may receive a touch input of the user and may provide response content in response to the touch input on the region 320.

FIG. 4 is a flowchart of a method of providing advertising content, according to an exemplary embodiment.

As shown in FIG. 4, in operation S410, the display device 110 may form a first pairing with a first terminal. The display device 110 may periodically broadcast an advertising message including an ID of the display device 110. The first terminal that is located in the vicinity of the display device 110 may receive the advertising message, and may recognize the ID of the display device 110 in the advertising message. The first terminal may transmit an ID and information of the first terminal to the display device 110.

In operation S420, the display device 110 may obtain first advertising content that is searched from the advertising server 130. The advertising server 130 may obtain the first advertising content based on first shopping propensity information of a user of the first terminal. The advertising server 130 may be a storage medium (e.g., memory) that is provided in the display device 110 or an external apparatus that is physically separate from the display device 110. Examples of the first advertising content may include a moving image and a photograph.

The first shopping propensity information may be determined based on at least one of a purchased product, a store, a time of purchase, a payment method for the purchased product, and interests of the user of the first terminal.

According to an exemplary embodiment, the first shopping propensity information of the user of the first terminal may be established as data that is accumulated in the advertising server 130 as the user shops in a store.

According to another exemplary embodiment, the first shopping propensity information of the user of the first terminal may be established as the user joins a preset Internet site and inputs information about the user. The advertising server 130 may receive the information of the user from a server of the preset Internet site.

In operation S420, the display device 110 may obtain an ID of the first terminal and may transmit the obtained ID to the advertising server 130. The advertising server 130 may obtain the first shopping propensity information of the user by using the obtained ID. The advertising server 130 may detect first advertising content that is suitable for the user by using the first shopping propensity information of the user.
